While tipping carpet installers is ultimately a personal decision, it is generally not necessary. Contractors, such as carpet installers, typically charge the customer a fair price for the planned work and do not anticipate a tip.
Because some companies prohibit workers from accepting tips, individuals who plan on tipping their carpet installers should contact the owner of the company first. If tips are allowed, cash is the most common form of gratuity. As of 2015, individuals who tip tradespeople usually give less than 20 percent of the total cost of the work. If tips are prohibited, individuals can show their appreciation by writing a positive online review or praising the workers in a letter addressed to the company's owner.
